The spin and orbital-current contributions to isovector $M1\mathrm{}$ transitions in light nuclei are studied using shell model wave functions. An impressive effect of the orbital magnetization is predicted for ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ and demonstrated by comparing the $M1\mathrm{}$-strength distributions for inelastic electron scattering with the distribution for radiative pion capture and ($p, n$) reactions.
